我尝试调整this tutorial以便与TextView和Button一起使用。我已创建了ArrayList和ListView：
private void displayListView() {
//putting two Country objects into the ArrayList
//these countries have email addresses for some reason, just go with it
ArrayList<Country> countryList = new ArrayList<Country>();
country = new Country("email@email.com","DummyName1",false);
countryList.add(country);
country = new Country("email@email.com","DummyName2",false);
countryList.add(country);
//create an ArrayAdaptar from the String Array
dataAdapter = new MyCustomAdapter(this,
R.layout.pending_invite, countryList);
ListView listView = (ListView) findViewById(R.id.listViewPendingRequests);
// Assign adapter to ListView
listView.setAdapter(dataAdapter);
}
这是我的主要XML：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/listViewPendingRequests" />
</LinearLayout>
这是我的pending_invite.xml：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/linearLayout" >
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Pending Invitation 1"
android:id="@+id/textView7"
android:layout_weight="1" />
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Cancel"
android:id="@+id/button5"
android:layout_weight="1"
android:onClick="onClickCancel"/>
</LinearLayout>
</LinearLayout>
我认为，由于我不再需要复选框和内容，因此无法制作MyCustomAdapter。无论如何，这是我到目前为止所得到的：
private class MyCustomAdapter extends ArrayAdapter<Country> {
private ArrayList<Country> countryList;
public MyCustomAdapter(Context context, int textViewResourceId,
ArrayList<Country> countryList) {
super(context, textViewResourceId, countryList);
this.countryList = new ArrayList<Country>();
this.countryList.addAll(countryList);
}
private class ViewHolder {
TextView code;
Button name;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
Log.v("ConvertView", String.valueOf(position));
if (convertView == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(
Context.LAYOUT_INFLATER_SERVICE);
convertView = vi.inflate(R.layout.pending_invite, null);
holder = new ViewHolder();
holder.code = (TextView) convertView.findViewById(R.id.textView7);
holder.name = (Button) convertView.findViewById(R.id.button5);
convertView.setTag(holder);
}else {
holder = (ViewHolder) convertView.getTag();
}
Country country = countryList.get(position);
holder.name.setText(country.getName());
holder.name.setTag(country);
return convertView;
}
}
这样（令人惊讶地）构建视图，但是如何判断onClick中哪个被按下了？：
public void onClickCancel(View view){
Log.i(LOG_TAG, "OnClickCancel view: " + view.getId()); //getId returns the same thing for all clicks. How do I get which button clicked?
}
view.getId为所有按钮返回相同的ID。如何将onClick侦听器附加到自定义视图中的膨胀按钮？

你可以做这样的事情
private class MyCustomAdapter extends ArrayAdapter<Country> {
private ArrayList<Country> countryList;
public MyCustomAdapter(Context context, int textViewResourceId,
ArrayList<Country> countryList) {
super(context, textViewResourceId, countryList);
this.countryList = new ArrayList<Country>();
this.countryList.addAll(countryList);
}
private class ViewHolder {
TextView code;
Button name;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
Log.v("ConvertView", String.valueOf(position));
if (convertView == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(
Context.LAYOUT_INFLATER_SERVICE);
convertView = vi.inflate(R.layout.pending_invite, null);
holder = new ViewHolder();
holder.code = (TextView) convertView.findViewById(R.id.textView7);
holder.name = (Button) convertView.findViewById(R.id.button5);
convertView.setTag(holder);
}else {
holder = (ViewHolder) convertView.getTag();
}
Country country = countryList.get(position);
// holder.code.setText(" (" + country.getCode() + ")");
holder.name.setText(country.getName());
//holder.name.setChecked(country.isSelected());
holder.name.setTag(countryList.get(position).getName()); // here you are setting the tag, it will be retrieved in handleClick method
// here create your on click handler, like
holder.name.setOnClickListener(handleClick(holder.name));
return convertView;
}
}
此处定义您的handleClick方法
private OnClickListener handleClick(final Button butn) {
// TODO Auto-generated method stub
return new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
String TAG = butn.getTag().toString(); // get the tag, now you can compare which button has been clicked with respect to its tag name
if (TAG.equals("somehting")
{
// your logic here
}
}
};
}
我希望你从这个答案中得到一些想法。

在国家/地区中创建归档的“ID”。然后在创建Country实例时为每个对象分配一个值。然后在类国家/地区内为按钮添加onclick侦听器，并传递位置。然后使用以下函数获取单击
public void onClickCancel(int position){
Country country = countryList.get(position);
String countryId = country.ID;
Log.i(LOG_TAG, "OnClickCancel view: " + countryId );
}

请尝试这种方式，希望这有助于您解决问题。
private class MyCustomAdapter extends ArrayAdapter<Country> {
private ArrayList<Country> countryList;
private Context context;
public MyCustomAdapter(Context context, int textViewResourceId,
ArrayList<Country> countryList) {
super(context, textViewResourceId, countryList);
this.countryList =countryList;
this.context = context;
}
private class ViewHolder {
TextView code;
Button name;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
Log.v("ConvertView", String.valueOf(position));
if (convertView == null) {
convertView = LayoutInflater.from(context).inflate(R.layout.pending_invite, null);
holder = new ViewHolder();
holder.code = (TextView) convertView.findViewById(R.id.textView7);
holder.name = (Button) convertView.findViewById(R.id.button5);
convertView.setTag(holder);
}else {
holder = (ViewHolder) convertView.getTag();
}
holder.name.setText(countryList.get(position).getName());
holder.name.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(context,countryList.get(position).getName(),Toast.LENGTH_SHORT).show();
}
});
holder.name.setOnClickListener(handleClick(holder.name));
return convertView;
}
}

如果您只想捕获onClick for按钮，则必须为按钮实现onClickListener：holder.name
holder.name.setOnClickListener（new View.OnClickListener（）{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
如果要获取单击的项目，请为列表视图设置setOnItemClickListener。或者只是setOnClickListener用于你的customView convertView.setOnClickListener（new View.OnClickListener（）{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
